The objective of the present study was to evaluate the effects of coffee intake with and without caffeine on feeding behavior in rats. Sixteen rats was exposed to 2g, 3g, 4g and 5g of coffee with caffeine and without caffeine diluted in 200ml of water. Subjects were assigned to 4 groups conformed by 2 females and 2 males each one. Groups 1 and 2 were exposed to coffee with caffeine and groups 3 and 4 to coffee without caffeine. Exposed to coffee for groups 1 and 3 was of ascending form (2 g, 3 g, 4 g, and 5 g) and for groups 2 and 4 of descendent form (5 g, 4 g, 3 g and 2 g). The experiment was divided in 9 phases. Phases 1, 3, 5, 7 and 9 lasted of 10 days, in each one were provided 200ml of water and 50g food. Phases 2, 4, 6 and 8 lasted of 5 days; in each one provided the concentrations of coffee and 50g food. The results showed that the low concentrations of coffee registered a greater consumption in comparison with the high concentrations in both conditions (ascending and descendent). On the other hand, coffee without caffeine was more consumed than coffee with caffeine
